    摘要: The present invention concerns a method for manufacturing patterned porous substrates with hidden color patterns by forming hydrophobic patterns on a hydrophilic surface, wherein structural channels are formed as a pattern in a porous substrate using a hydrophobic printing solution lacking colorant, and wherein a colored area is applied on the rear surface of the porous substrate. Further, the present invention concerns said patterned porous substrate and a method for bringing said pattern into a visible state.

    摘要: The invention relates to the production of an optically detectable marking on a substrate. In the method, a substrate is taken, a printing ink containing a starch derivative in a solution form is printed on at least a selected first area and at least a selected second area is left unprinted, the printing ink is allowed to dry, in such a way that the starch derivative form a thermoplastic film in the said first area on the surface of the substrate, and an optically detectable marking is hot-pressed into the film. The invention also relates to a corresponding product. With the aid of the invention hot-pressable diffractive embossing is created at low temperatures, for example, on paper or board.
